<u><em>Answer:</em></u>

The intersection point is (-4,-19)

<u><em>Explanation:</em></u>

<u>The two given equations are:</u>

y = 5x + 1

y = 2x - 11

<u>To find the intersection point, we will start by equating the two given equations and solving for x</u>

<u>This is done as follows:</u>

5x + 1 = 2x - 11

5x - 2x = -11 - 1

3x = - 12

x = -4

<u>Then, we will use the x and substitute in any of the equations to get the value of y</u>

<u>Using the first equation:</u>

y = 5x + 1 = 5(-4) + 1 = -19

<u>Check using the second equation:</u>

y = 2x - 11 = 2(-4) - 11 = -19 ................? checked

<u>Therefore:</u>

The intersection point between the two given equations is (-4,-19)

Hope this helps :)

Samuel deposits $1,800 in an account that earns 12% simple annual interest. How many months will it take for Samuel's account ba
Artemon [7]
In order to use the simple interest formula, we first define the variables. The interest would be equal to Samuel's desired amount $ 2,488 minus the principal amount of $ 1,800 which is then equal to $ 688. The rate must be in decimal form which is equal to 0.12 while t is expressed in years. Substituting the values, t is equal to 3. Thus, it will take 36 <span>months for Samuel's account balance to reach $2,448. </span>

Riangle XYZ was dilated by a scale factor of 2 to create triangle ACB and sin ∠X = 5 over 5 and 59 hundredths.
DochEvi [55]

Answer:

Step-by-step explanation:

1. Part A: We know parts of our triangle since the cosine of X is given.  XY = 2.5 and XZ = 5.59 and since it is a scale factor of 2, ABC is most likely similar to XYZ by angle measures and the special relationship is, that they are all equal, because with a scale factor of two, all the ratios in triangle ABC will simplify to the ratios of triangle XYZ. 

Part B: Because triangle XYZ was dilated with a scale factor of 2 to create triangle ABC, just multiply the sides by 2 to get the sides AC and CB, which is AB = 2 times XY and CB = 2 times XZ. 

2. We can first find the hypothenuse by adding squaring 8 and 6 to have 100. Then square root it to have 10 as our hypothenuse

Now we can use sin x = 6/10 and cos y = 6/10

3. Since this is using the angle of elevation, we can say that the length of side AB is perpendicular from the perspective of angle of elevation, and the hypotenuse's length is known, so in this case, we can use a sine or cosecant ratio. 

Sin(40 Degrees) = AB/100

AB = 100 x sin(40 Degrees) ft

AB ~ 64.28 ft which can be rounded to 64 ft

The triangle I drew was a right triangle with points A, B, and C. 40 is on point C while 100 ft was on the hypotenuse. The kite was near A and the ground was between segment B and C.

4. Since the angle and Adjacent line is given and it is asking us to find H which is the opposite, we well try and be using Tangent = opposite/adjacent 

500 ft Multiply by tan39 = 405 (Estimated after rounding to nearest hundreth 404.892).

To be honest, I didn't know so much about these questions but this might give a better understanding and if I'm wrong then I apologize.
